Hello. I found this strange.. Piece of paper at the playground. I go there everyday; I met some new people there today. I met this "caretaker" guy. She said she protected the playground and the other.. Uh.. How do I say this.. "stupid things in the world" is a good way to say it. There was lots of pieces of paper on the playground;one said: 抱歉. I bet its some secret lettering. Eh, who cares? Who even put those there... Well, that's some thing to think about. Maybe Mrs. Caretaker?
